A portable application can be run from a removable drive (USB flash drive, iPod, portable hard drive, etc) on any Windows computer without installation.
You will carry the program with settings on removable drive and don't modify settings on host computer.
On Vista and above turn off User Account Control (UAC) or run launcher as admin.

And finally, now, portable version 1.0.6 it's working perfectly!It was driving me mad, I had started to track and debug the main process to look for the problem. But I couldn't find it...Anyway, as always, thanks Bernat for your time, knowledge and portable contributionz!!Thumbs up for you.
